SMOKING PIPE, CIGAR, OR CIGARETTE HOLDER Filed Feb. 24, 1958 )2 szfirizz Patented Nov. 12, 1940 UNITED STATES SMOKING PIPE, CIGAR, OKCIGARETTE HOLDER Roy Brigham, Toronto, Ontario, Canada ApplicationFebruary 24, 1938, Serial No. 192,341 In Canada April 30, 1937 Claims.(01. 131-204) This invention relates to an improved type of a stem forsmoking pipe, cigarette holder and the like and has for'its objectremoving from the tobacco smoke, the tars, volatile oils, and othermoisture and disposing of them in such a manner as to substantiallyprevent their being carried into the mouth of the smoker and, at thesame time, prevent the pipe, cigar or cigarette holder from becomingrancid.

For an understanding of this invention and the manner in which the abovementioned objects are obtained, reference is to be had to the followingdescription, illustrated by the accompanying drawing in which:

15 Figure 1 is a cross sectional view of a pipe embodying the subjectmatter of this invention;

Figure 2 shows a cross section of the improved pipe with stem detached;

Figure 3 shows a cross sectional view of the 20 mouthpiece of the pipewith the porous smoke duct removed; and

Figure 4 shows a cross sectional View of the porous smoke duct.

Like characters of reference refer to like parts 25 throughout thespecification and drawing.

The pipe illustrated in the drawing comprises a bowl II! having a shankII extending outwardly therefrom and preferably from the base thereof.The mouthpiece I2 is connected to the shank I I in the usual manner.

The passageway or smoke duct I3 is formed in the mouthpiece I2 and iswidened as indicated at I4 to receive the non-porous tube I5. Thenonporous tube I5 is preferably fabricated from 3 metal, such asaluminum or an alloy thereof, and

extends into the shank II approximately to the bowl III of the pipe.

The inner surface of the shank II is cut away as indicated to form aclosed air chamber I6 between the tube I5 and the inner surface of theshank I I. The air chamber I6 serves a dual purpose inasmuch as it tendsto ease the passage of the tube I5 into the shank II when attaching themouthpiece thereto and when the shank II is in place tends to keep theouter surface of the tube I5 cool. The tube I5 makes a snug andsubstantially air-tight fit with the shank I I approximate to the bowlwhile the other end makes a substantially air-tight fit in the bore ofthe mouth- 50 piece I2.

The porous tube I'I, formed for example of light wood which has beencured to open the pores, is removably entered into the non-porous tubeI5. One end of the porous tube I1 is provided with a 55 nipple It. Thenipple I8 is preferably of metal and tapered to engage with the innersurface of the forward end of the tube I5 and in substantially air-tightengagement therewith. The porous tube I1 is substantially the samelength as the non-porous tube I5 and terminates at the mouthpiece end ofthe tube I5 making a substantially air-tight fit with the mouthpiece I2.The nonporous tube I'I forms a continuation of the passageway I3 andprovides a smoke duct between the bowl III of the pipe and thepassageway I3 10 formed in the mouthpiece I2.

When the various parts of the pipe are assembled, the air chamber I9 isformed between the outer surface of the porous tube I1 and the innersurface of the non-porous tube I5. The air chamber I9 forms an essentialpart of my invention.

I have found my invention in operation removes the tars, volatile oilsand moisture from the smoke during its passage through the porous tubeI1. The tars collect on the inside surface of the porous tube, theVolatile oils are absorbed into the pores thereof while the moisturepasses through the pores into the air chamber I9 from which it may bereadily removed periodically by separating the mouthpiece I2 from theshank II, taking the porous tube I'I out of the non-porous tube I5 andgiving the mouthpiece a slight shake. The tars are easily removed fromthe interior of the porous tube I! by passing a pipe cleaner through. Onexposure to the air for a few minutes, the volatile oils evaporate asdoes the remainder of the moisture, and the tube is again ready for use.

I have found also that pipes, and the like, embodying my invention donot become rancid or 5 sour as is common in pipes where no provision ismade to prevent the fermentation of the volatile oils and tars. Inaddition, it is not necessary to provide filters or any otherobstructions in the smoke duct to impede the passage of those 40impurities to the mouthpiece.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

l. A stem for pipes, cigarette holders and the like, comprising a smokeduct, a non-porous tube entered in said duct, and spaced from the wallthereof to form a closed chamber therebetween, and a porous tuberemovably fitted into said nonporous tube and spaced therefrom to form aclosed chamber.

2. A pipe of the class described comprising a bowl and stem, a smokeduct through said stem and having an enlarged portion, a non-porous tubebridging said enlarged portion forming a .65

closed chamber between the inner wall of the enlarged portion of theduct and the outer wall of said tube, and a removable porous tube fittedinto the non-porous tube and spaced therefrom to form an air chamberbetween the inner wall of the non-porous tubeand the outer wall of theporous tube.

3. A pipe of the class described, comprising a bowl and a stem, a smokeduct through said stem and having an enlarged portion, a non-porous tubebridging said enlarged portion forming a closed chamber between theinner wall of the enlarged portion of the duct and the outer wall ofsaid tube, and a removable porous tube smaller than the non-porous tubefitting into said nonporous tube and spaced therefrom by a metal nippleattached to one end of the porous tube, thus forming a closed chamberbetween the inner wall of the non-porous tube and the outer wall of theporous tube.

" 4. A pipe of the class described, comprising a bowl, a stem, and amouthpiece, a smoke duct through said stem and having an enlargedportion, a nonporous tube attached to the mouthpiece, said tube bridgingsaid enlarged portion of the smoke duct and forming a chamber betweenthe inner wall of the enlarged portion of the duct and the outer wall ofsaid tube, and a removable dried wooden tube of smaller diameter fittinginto said non-porous tube and spaced therefrom by a tapered nippleattached to one end of the dried wooden tube, said tapered nippleengaging the inner portion of the non-porous tube which bridges theenlarged portion of the'smoke duct, to form a closed chamber between thenon-porous tube and the removable wooden tube.

5. A pipe of the class described, comprising a bowl, a stem, and amouthpiece, a smoke duct through said mouthpiece and stem leading to thebottom of the bowl, the smoke duct through the entire stem being oflarger diameter than the rest of the smoke duct, a metal tube attachedto the mouthpiece and extending therefrom to the bottom of the bowl, anda removable dried wooden tube within the metal tube and positionedtherein out of contact with the Wallsthereof by a metal nipple, saidwooden tube being removable from the stem with the metal tube and themouthpiece.
